On a more serious note from my last comment though, I dont think it matters wat breed/size of dog you choose.. just as long as you chose one with the same personality as your dog. my dad had a Huge lurcher and a border terrier and they were brill together.. both relaxed in the house and used all their energy chasing in circles (ok well with the border yipping cos he couldnt keep up! lol)
and my friend has a Newfie and a Pom who love eachother
